COMBINATION-TOOL.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application filed November 21, 1916. Serial No 132,655.

To all whom it may concern:

Be it known that I, ANTONIO G. SILVA, a citizen of the United States, residing at Honolulu, in the country of Honolulu, and in the Territory of Hawaii, have invented new and useful Improvements in Combination-Tools, of which the following is a specification.

This invention relates to improvements in combination tools and has for its principal object to provide a tool in the form of a punch, the shank of which is formed of a plurality of separable elements, each of which is adapted to carry tools of various descriptions.

Another characteristic of this invention is to provide a device of the above described character in which the punch point is removably mounted upon the shank to permit the interchanging of the point in the event that it becomes worn or broken.

Another object of this invention is to pro vide a device of this character which contains the desirable features of simplicity, durability and efliciency and furthermore to so arrange the tools that they will be completely incased to prevent the accidental breaking of the same.

Other objects of the invention will appear as the specification is read in connection with the accompanying drawings in which Figure 1 is a side elevation of the device constructed in accordance with my invention;

Fig. 2 is a longitudinal section of the same;

Fig. 3 is an end elevation.

Referring to the drawings in detail, my invention comprises a shank which is formed of a plurality of separable sections, I having shown in this instance three of said sections, the end sections being indicated as at 1 and 2 respectively, and the intermediate section as at 3. The sections 1, 2 and 3 are formed of any suitable metal such as steel or the like and are preferably circular in cross section.

The end section 1 has its free end provided with an enlarged head 4, the said head being preferably circular in cross section and secured to the section 1 at its medial portion. The head 4 is purposely designed to be used as a hammer and has one side rovided with the laterally extending spaced ugs 5 which serve the purpose of a nail extractor. The opposite or inner end of the section 1 is provided centrally thereof with a longitudinally extending bore 6 the wall of which is threaded to receive a threaded extension 7 formed on the intermediate section 3. The bore 6 is of such a length as to readily accommodate a screw driver 8 which is formed on the free end of the ex tension 7. The intermediate section 3 is provided upon its outer surface with a longitudinally extending flange 9 which is designed for the purpose of assisting in the operation of the screw driver as wlll be understood. The opposite end of the intermediate section 3 is provided centrally thereof with a longitudinally extending bore 10, the interior of which is threaded to receive the threaded extension 11 formed on the confronting end of the end section 2.

The section 2 is provided centrally thereof with a longitudinally extending tapering bore 12, its smaller end extending through the extension 11 while its larger end is in communication with a relatively larger bore 13 which is formed in the opposite end of the section as is clearly illustrated. The tapering bore 12 is adapted to receive an awl 14, the bore 10 of the intermediate section 3 being of such a length as to readily accommodate the free end of the aw]. The awl is preferably provided at one end thereof with a shoulder 15 which is adapted to engage with the shoulder formed at the intersection with the bores 12 and 13. The

shoulder which is indicated as at 16, is adapted to limit the outward movement of the awl as will be understood. The outer end of the section 2 as previously described is provided with a relatively large bore 13 which is interiorly threaded to receive a reduced extension 17 formed on the punch 18. The punch 18 is of conical formation and is preferably formed of hard steel to efficiently perform the function for which it is intended. The inner end of the extension 17 is provided with an car 19, the latter being adapted to receive a flexible element such as a cord whereby the punch 18 may be used as a plumb bob when the same is detached from the section.

It will be manifest from the foregoing construction that I have provided a plurality of separable sections certain of which are provided with extensions and pockets to receive the extensions, the pockets and extensions being threadedly engageable with each other to lock the sections in assembled formation. It will be noted that thesections carry different classes of tools, -ancl-- will be evident that by removing one of the 10 sections the length of the shank will be varied accordingly. In providing one of the sections with the enlarged head t, the head produces an efiicient anvil upon which the tool is adapted to be struck when forcing the punch within the work as will be understood.

It is thought from the foregoing .taken in connection with the accompanying drawings that the construction and operation of my device will be apparent to those skilled in the art, and that minor changes in the size,

shape and proportion and minor details of construction may be made Without departing from the spirit andscop e. of the appended claims.

What I claim is z A tool comprising a handle part and a head part of cylindrical form, one-end of said head constituting a working part and having its central part secured to the handle, and a pair of laterally extending spaced lugs projecting from the head'niid way of its ends and at rightangles to the handle part,

said lugs being curved toward the handle and tapering from their base toward their free ends and the curve of their outer sides forming a continuation of the circumference of the head, and said curve beginning at a point diametrically opposite the connection of the head with the handle.

In testimony whereof I EtfllX my signature.
